Dormakaba CA250 – Frequently Asked Questions

1) How many doors and readers will the Keyscan CA250 control unit handle?
The dormakaba Keyscan CA250 is a two-door panel, supporting two readers and two doors from a single unit. It carries two door output relays for the locks plus two auxiliary output relays for other devices, and four supervised inputs for things like request-to-exit, door position switches, or tamper. If you need more openings on one board, Keyscan builds the same control unit family in 4 and 8 door versions.
2) Is the CA250 a power supply, or do I need to power it separately?
The CA250 is an access control unit, the panel that makes the lock and reader decisions, not a lock power supply. It has a PoE enabled Ethernet port, so the board itself can take power over the network cable, but your electric strikes, mags, or electrified exit devices still need their own DC supply. A boxed 12/24VDC supply like the Securitron AQL4 or the Von Duprin PS902 is the usual companion for the lock side.
3) Will the CA250 work with my existing card readers?
Reader settings on the CA250 are configurable on the board and support many Wiegand protocols, so most standard Wiegand proximity, smart card, and keypad readers will land on it. Wiring is two readers per panel. If your readers are OSDP-only or use a proprietary non-Wiegand output, they are not a fit for this panel.
4) Can I link several CA250 panels together for a building-wide lockdown?
Yes, the CA250 supports lock down and global communication between multiple access control units, the server, and across sites. That is what lets a school or hospital drop every door at once from a single command. It is not built into the panel alone though: global and lockdown functions require CIMs and CIM Link, so budget those into the system design.
5) Does the DormaKaba CA250 replace a power supply like the Von Duprin PS902 or the Altronix AL1024ULACMCB?
No. The Keyscan CA250 is a 2 reader/door access control unit - it makes the access decisions, holding up to 45,000 credential holders, with (4) supervised inputs, (2) door output relays and (2) auxiliary output relays, and a network TCP/IP connection back to the server. The Von Duprin PS902 is a base power supply rated 2A at 12/24VDC field selectable, and the Altronix AL1024ULACMCB is a power supply/access power controller taking 115VAC 60Hz input at 4.2A and delivering 24VDC at 10A across 8 PTC outputs. Those units supply and distribute lock power; the CA250 does not. On a typical two-door job you buy both - a controller and a power supply feeding the locks.
6) What power supply should I pair with a DormaKaba CA250 for two electric strikes?
The CA250 switches locks through its (2) door output relays but the lock current comes from a separate supply. Options in a 12/24VDC lock power range include the RCI DKPS-2A, which gives 8 outputs at 12/24VDC 2A, the Securitron AQL4 switching supply at 12/24VDC 4/3A, the SDC 632 Series 2 amp regulated and filtered supply with dual voltage selection, and the Command Access PS204/204B linear supply at 2A 24VDC with battery backup. Pick the voltage your strikes call for and size the amperage to the total inrush of both doors plus any readers fed from the same supply.
7) My openings are motorized latch retraction exit devices. Does the CA250 drive them directly?
No. Motorized latch retraction draws a heavy inrush that needs a dedicated supply - the BEST RPSMLR2 Series is a power supply built for motorized latch retraction exit devices, and the BEST ELR150 Series is a power supply control module for electronic access control. The CA250 provides the access decision and switches through its (2) door output relays; run those relays as the trigger into an MLR supply rather than powering the device from the control unit.
8) How many cardholders can a Keyscan CA250 panel hold?
45,000 credential holders are stored on the CA250 panel itself, in flash memory. For a multi-family property or a mid-size commercial building that is more than enough headroom to hold every tenant, employee, and contractor card in the database locally, so the panel keeps granting access when the server or network is down.
9) What happens to access records if the network connection drops?
The CA250 runs an auto-transfer protocol: if communication to the server is interrupted, the panel buffers transactions and uploads the buffer once the link is restored. Nothing in the audit trail is lost during the outage. Dual on-board processors handle the decision-making locally, so doors keep working off the cardholder data already stored on the board.
10) I just need to power one electric strike. Is a CA250 overkill?
For a single opening with no cards, credentials, or audit trail, yes. The CA250 is a networked two-door control unit with a 45,000 cardholder database. If all you need is regulated DC to hold a strike or mag, a small supply like the SDC 620 Series 1 amp unit, the Command Access PS1 24VDC supply, or the ROFU 9126T plug-in mini supply with time delay does that job instead.
11) What is the difference between the CA250 and an access power controller like the Altronix AL1024ULACMCB?
They do different halves of the job. The CA250 reads credentials, holds the cardholder database, and decides who gets in over TCP/IP. The Altronix AL1024ULACMCB is a power supply and access power controller, 115VAC input, 24VDC at 10A across 8 PTC outputs, which distributes and switches power to the locks once something else makes the decision. On a larger system you often see both: the controller for the logic, the Altronix for the lock power.
12) I only need one door with a keypad release, not a networked system. Is there something simpler than the CA250?
For a single opening with no card management, host software or network reporting, a standalone supply with built-in release timing covers it - the ROFU 9126T is a plug-in mini power supply, 12VDC at 1.5A with time delay, and the SDC 631 Series is a 1.5 amp regulated and filtered DC power controller with dual voltage selection. Step up to the CA250 when you need credentials rather than a button: it is a 2 reader/door control unit, TCP/IP ready, with configurable reader settings supporting many Wiegand protocols and capacity for 45,000 credential holders.
13) Is the Detex 10-800 Series universal logic controller an alternative to the Keyscan CA250?
They control doors in different ways. The Detex 10-800 Series is a universal logic controller with a 120VAC/24VDC power supply and battery backup, handling local door logic and sequencing at the opening. The CA250 is a credential-based access control unit for 2 readers/doors with dual processors, flash memory, DHCP support and a PoE enabled Ethernet port, plus an auto-transfer protocol that uploads the transaction buffer if communication is interrupted. If you need cardholder records, transaction history and remote administration, the CA250 is the one that carries that; if you need hardwired logic and onboard power at a single opening, the Detex unit addresses that.
14) Can I use the Aiphone AC-PS1250 instead of the CA250 in an Aiphone AC Series access control kit?
The Aiphone AC-PS1250 is the 12VDC 5A UL listed power supply for AC Series access control kits - it powers that system, it does not replace a control unit. The Keyscan CA250 is the panel itself: 2 readers/doors, network TCP/IP ready, with (4) supervised inputs and (2) door plus (2) auxiliary output relays for expansion. The two are different elements of a system rather than substitutes for one another.
15) Do I need a supply with battery backup alongside the Keyscan CA250?
If the openings have to stay controlled through a utility outage, yes - the CA250 holds its cardholder data in flash memory and its auto-transfer protocol uploads the transaction buffer when communication is restored, but locks still need power. Supplies in the set that carry backup include the Adams Rite PS-1 regulated power supply at 1 amp 12/24VDC with battery backup, the Command Access PS204/204B at 2A 24VDC with battery backup, and the Detex 10-800 Series 120VAC/24VDC unit with battery backup. Size to the fail-secure or fail-safe behavior of your locks, since fail-safe hardware draws continuously on the battery.
16) I have four doors to control. Should I buy two CA250 units?
The CA250 is a 2 reader/door control unit, so four openings would take two of them. Keyscan builds 2, 4 and 8 door control units on the same platform, all with dual on-board processors and heavy duty relays, so a single 4-door unit is the other route. Either way the panels share lock down and global communication across multiple ACUs, server and sites, which requires CIMs and CIM Link.
17) Will a Securitron AQS1210 or SDC 634 power supply do the job of the CA250 on an access control project?
They fill the power half of the project, not the control half. The Securitron AQS1210 is a switching power supply at 12VDC 10 amp and the SDC 634 Series is a 4 amp regulated and filtered low voltage supply with dual voltage selection - both are sized to feed multiple locks and readers. Neither reads credentials or reports to a server. The CA250 is the unit that does that, with configurable reader settings supporting many Wiegand protocols, a PoE enabled Ethernet port and DHCP support, and capacity for 45,000 credential holders.
18) Does the CA250 need a static IP address, or can it pull one from the network?
DHCP is supported on the CA250, so it can take an address from the network automatically, and the panel is TCP/IP ready out of the box. Most integrators still assign a reservation or static address on a controller so the head-end software always finds it at the same place, but you are not forced to.
19) Can I run an alarm output or a door bell off the CA250 besides the locks?
Two auxiliary output relays sit on the board on top of the two door relays, so you have contacts available for an alarm shunt, a siren, a door-forced annunciator, or lighting. Paired with the four supervised inputs, that gives you room to bring in door contacts and REX and still trigger something else.
20) Is there a controller option that includes its own power supply and battery backup instead?
If you want logic and power in one enclosure, the Detex 10-800 Series universal logic controller ships with a 120VAC/24VDC power supply and battery backup. It is a different animal from the CA250, which is a networked card access panel rather than a standalone logic board, but for a single controlled exit where you are not running a credential database it can be the simpler install.
